<First Embodiment>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing a refrigerator according to an embodiment. The refrigerator 1 is provided with a refrigerator compartment 2 at the top of a heat insulating box (not shown). Below the refrigerating room 2, an ice making room 3 and a freezing room 4 are arranged side by side. A freezing room 5 is provided below the ice making room 3 and the freezing room 4, and a vegetable room 6 is provided below the freezing room 5.

  The refrigerator compartment 2 stores the stored items in a refrigerated state, and the vegetable compartment 6 maintains the temperature higher than the refrigerator compartment 2 to store the stored items such as vegetables in a refrigerator. The ice making room 3, the freezing room 4, and the freezing room 5 communicate with each other, ice making and ice storage are performed in the ice making room 3, and stored items are stored frozen in the freezing rooms 4 and 5.

  The refrigerator compartment 2 is opened and closed by double doors 11 and 12 pivoted at the left and right ends, respectively. The ice making chamber 3 is opened and closed by a drawer type door 13 integrated with an ice storage container (not shown). The freezer compartments 4 and 5 are opened and closed by drawer type doors 14 and 15 integrated with a storage case (not shown) for stored items, respectively. The vegetable compartment 6 is opened and closed by a drawer-type door 16 integrated with a vegetable case (not shown). The doors 11 to 16 are filled with a foam heat insulating material 38 (see FIG. 2).

  FIG. 2 is a perspective view of the door 15 of the freezer compartment 5 and shows a cross section cut along the line AA in FIG. The door 16 of the vegetable compartment 6 is formed similarly. 1 and 2, the door 15 is formed in a rectangular shape when viewed from the front, and is covered with an upper surface cover 31, a lower surface cover 34, side surface covers 32 and 33, a back cover 35, and a glass plate 37.

  The upper surface cover 31 (cover member), the lower surface cover 34, the side surface covers 32 and 33, and the rear surface cover 35 are formed of a resin molded product and cover the upper surface, the lower surface, both side surfaces, and the rear surface of the door 15, respectively. For example, the glass plate 37 is formed of soda glass having a thickness of 3.2 mm and covers the front surface of the door 15.

  A holding member 36 of a resin molded product is disposed at the center in the left-right direction of the door 15 along the upper side of one side of the door 15. The holding member 36 covers the front surface of the door 15 and forms a recess 40 with the upper surface and the front surface opened. Thereby, the recess 40 is formed in the center of the upper side of the door 15. A fitting portion 36a is provided at the upper end of the holding member 36 to be fitted to a rib 31a protruding from the upper surface cover 31, and a holding portion 36b is provided at the lower end to hold the glass plate 37 therebetween.

  Thereby, even if the shrinkage amount of the upper surface cover 31 and the holding member 36 is different due to the shrinkage force of the foam heat insulating material 38, it is absorbed by the gap between the fitting portion 36a and the rib 31a. Therefore, the deformation of the door 15 due to the shrinkage of the foam heat insulating material 38 can be prevented.

  The upper surface cover 31 has a handle portion 39 that is disposed in front of the recess 40 with its front end bent downward. A finger inserted into the recess 40 can be hung on the handle 39 and the door 15 can be pulled open. Since the recessed part 40 is provided in a part of the upper side of the door 15, the thickness of the door 15 in the part adjacent to both sides of the recessed part 40 can be increased. Thereby, the heat insulation of the door 15 can be improved.

  FIG. 3 shows a front view of the glass plate 37. The upper cover 31, the lower cover 34, and the side covers 32 and 33 are formed with holding parts similar to the holding part 36b (see FIG. 2) of the holding member 36, and the glass plate 37 is surrounded by each holding part including the holding part 36b. Is retained. A notch 41 cut out along the recess 40 (see FIG. 2) is provided at the center of the upper end of the glass plate 37. Thereby, the part adjacent to the both sides of the recessed part 40 is covered with the glass plate 37, and it can prevent a damage over the wide range of the front surface of the door 15, and can improve cleaning property.

  The notch 41 is formed in a substantially trapezoidal shape having an open end along the upper side of the door 15. The notch 41 is formed by drawing a scribing line of a predetermined depth on the glass plate 37 by a scribing needle having a diamond piece, laser processing or the like, and breaking the scribing line with a finger or the like.

  At this time, both sides 41a intersecting the opening end of the notch 41 are inclined toward each other as the distance from the opening end increases, and the inclination angle θ of the side 41a with respect to the opening end forming surface is formed to be 65 ° or less. . When the inclination angle θ is larger than 65 °, the glass plate 37 is easily cracked when the notch 41 is folded, and the yield of the glass plate 37 is reduced. For this reason, it is necessary to form the notch 41 by cutting by machining, and the cost of the glass plate 37 increases.

  On the other hand, when the inclination angle θ is formed to be 65 ° or less, the glass plate 37 having the notches 41 can be easily formed with a high yield by folding with fingers or the like. For example, when the glass plate 37 is made of soda glass having a thickness of 3.2 mm or 4 mm, the glass plate 37 is manufactured with a yield that does not hinder manufacturing by forming a notch 41 having an inclination angle θ of 65 ° or less. I was able to.

  Further, if the corners of the base 41b and the side piece 41a facing the opening end of the notch 41 are curved, the cracks at the time of breaking the notch 41 can be further reduced. At this time, when the radius of curvature R of the corner was set to 30 mm or more, it was possible to almost prevent the glass plate 37 made of soda glass having a thickness of 3.2 mm or 4 mm from being cracked.

  According to the present embodiment, the concave portion 40 provided in a part of the upper side of the door 15 and the grip portion 39 for placing a finger inserted into the concave portion 40, and the glass plate 37 disposed on the front surface of the door 15 is formed in the concave portion 40. Since it has the notch part 41 notched along, the thickness of the door 15 of the part adjacent to the recessed part 40 can be enlarged. Therefore, the heat insulation of the door 15 can be improved and the power saving of the refrigerator 1 can be achieved. At this time, since the inclination angle of the side edge 41a with respect to the formation surface of the opening end of the glass plate 37 is set to 65 ° or less, the glass plate 37 can be broken along the marking line to easily form the notch 41. it can. Therefore, it is possible to improve the yield of the glass plate 37 and to prevent the scratches over a wide range of the front surface of the door 15 and improve the cleaning performance.

  Moreover, since the corner of the base 41b and the measurement side 41a which opposes the opening end of the notch part 41 was formed in the curved surface, the yield of the glass plate 37 can be improved more. At this time, when the radius of curvature of the corner is set to 30 mm or more, the yield of the glass plate 37 can be further improved.

  Further, the upper cover 31 (cover member) that covers the one end surface of the door 15 and forms the handle portion 39, the holding portion 36 b that holds the glass plate 37, and the fitting portion 36 a that fits the rib 31 a are recessed. And a holding member 36 forming 40. Thereby, even if the shrinkage amount of the upper surface cover 31 and the holding member 36 is different due to the shrinkage force of the foam heat insulating material 38, it is absorbed by the gap between the fitting portion 36a and the rib 31a. Therefore, the deformation of the door 15 due to the shrinkage of the foam heat insulating material 38 can be prevented.

  In this embodiment, although the recessed part 40 and the notch part 41 are provided along the upper sides of the doors 15 and 16 of the freezer compartment 5 and the vegetable compartment 6, on the upper sides of the doors 13 and 14 of the ice making chamber 3 and the freezer compartment 4 You may provide the same recessed part 40 and the notch part 41 along. Moreover, you may provide the recessed part 40 and the notch part 41 in a part of side edge along the side edge of the doors 11 and 12 of the refrigerator compartment 2. As shown in FIG.
